Question

6. Find the circumference of the inner and the outer circle, shown in the given
figure. (Take n = 3.14)​

Answer 1

Answer:

Radius of inner circle ( r ) = 19 - 10 = 9 m.

Therefore,

Circumference of inner circle = 2πR = 2 × 3.14 × 9 =56.52 m.

And,

Radius of outer circle ( R ) = 10 + 9 = 19 m.

Therefore,

Circumference of outer circle = 2πR = 2 × 3.14 × 19 = 119.32 m
